A tray-type optical splitter is a planar lightwave circuit (PLC) splitter housed in a tray-like structure, designed to divide a single optical signal into multiple outputs while enabling organized installation and protection in fiber optic networks.

Overview

A tray-type optical splitter is a passive optical device that splits one input optical signal into multiple outputs using PLC technology. The tray design allows the splitter to be neatly installed in fiber distribution boxes, optical distribution frames, or splice trays, providing both physical protection and efficient cable management . This design is particularly suitable for fiber-to-the-home (FTTH) networks, optical distribution networks (ODN), and CATV networks .

Key Features

• Compact and organized: The tray structure keeps fibers neatly arranged, reducing clutter and simplifying maintenance .
• High reliability: PLC technology ensures low insertion loss, high return loss, and uniform signal distribution across multiple outputs .
• Flexible installation: Can be mounted in standard fiber distribution frames, cross-connect cabinets, or optical fiber distribution boxes without strict environmental requirements .
• Customizable: Available in 1×N or 2×N configurations, with various connector types (SC, LC, FC) and fiber types to suit network needs .

Technical Considerations

• Wavelength range: Typically supports 1260–1650 nm, covering GPON, EPON, and XGS-PON applications .
• Splitting uniformity: Tested at standard wavelengths (1310 nm, 1490 nm, 1550 nm) to ensure consistent signal distribution .
• Environmental protection: The tray provides shielding against physical damage and environmental factors, enhancing durability .

Applications

Tray-type optical splitters are widely used in:

• FTTH deployments to connect a single optical line terminal (OLT) to multiple optical network terminals (ONTs) at customer premises.
• Optical distribution networks for efficient signal branching.
• CATV and broadband networks where high-density, reliable signal splitting is required. In summary, a tray-type optical splitter combines the precision of PLC technology with a practical tray design, offering a compact, reliable, and easy-to-install solution for modern fiber optic networks .
